Explanation: The first identified compact galaxy group, Stephan’s Quintet is featured in this remarkable image constructed with data drawn from Hubble Legacy Archive and the Subaru Telescope on the summit of Mauna Kea. The galaxies of the quintet are gathered near the center of the field, but really only four of the five are locked in a cosmic dance of repeated close encounters taking place some 300 million light-years away. The odd man out is easy to spot, though. The interacting galaxies, NGC 7319, 7318A, 7318B, and 7317 have a more dominant yellowish cast. They also tend to have distorted loops and tails, grown under the influence of disruptive gravitational tides. The mostly bluish galaxy, NGC 7320, is in the foreground about 40 million light-years distant, and isn’t part of the interacting group. Still, captured in this field above and to the left of Stephan’s Quintet is another galaxy, NGC 7320C, that is also 300 million light-years distant. Of course, including it would bring the four interacting galaxies back up to quintet status. Stephan’s Quintet lies within the boundaries of the high flying constellation Pegasus. At the estimated distance of the quintet’s interacting galaxies, this field of view spans over 500,000 light-years.
Tomorrow’s picture: crown of the sun
Nuclear Cat: We have a Hydrogen Bomb that Amigo found a couple of nautical miles up the inlet. All you need is one, and people will leave you alone, like that goof ball in North Korea. Except we wouldn’t let Dennis Rodman visit.
Amigo does a few maintenance things now and then, otherwise it seems to be ready-to-go.
The Editor: That certainly was fortunate. Did Amigo have a chance to recover the ones that crashed over North Carolina, or Spain ?
NC: Unfortunately no, at the time they were dropping more than the Kennedy Clan.
Glow Cat: It sure was, we tried this recipe for years but couldn’t get the recipe right.
The Editor: Did Putin make fun of Amigo, like he did O ?
Island Cat: No, but Amigo gave him one of our wild horses from Cumberland.
